Sudden Braking by Lead Vehicle Does Not Exonerate Following Vehicle from Maintaining Safe Distance and Duty of Control

On August 15, 2010, the deceased, Shri Adarsh Kumar Katiyar, was driving a Hyundai car from Jaipur to Delhi. Near Malpura Village, his vehicle collided with the rear of a tractor-trolley (offending vehicle) driven by Respondent No. 5 after the tractor suddenly applied brakes while taking a turn.

The Tribunal awarded compensation of Rs. 49,09,587, attributing 20% contributory negligence to the deceased for failing to maintain a safe distance.

The Appellant/Insurance Company challenged the award on three primary grounds: the inadequacy of the 20% contributory negligence assessment, the unauthorized commercial use of the tractor (carrying bricks in an un-insured trolley), and the alleged fake driving license of the driver.

1. Whether the assessment of 20% contributory negligence on the part of the deceased was appropriate given it was a rear-end collision.

2. Whether the attachment of a trolley laden with bricks to the insured tractor constituted a breach of policy conditions.

3. Whether the driver-cum-owner possessed a valid and effective driving license at the time of the accident.

The court applied Rules 23 and 24 of the Rules of the Road Regulations, 1989, which mandate following vehicles to maintain a "sufficient distance" while prohibiting "abrupt braking" by lead vehicles.

It relied on Nishan Singh v. Oriental Insurance Co. Ltd. regarding the duty of rear vehicles in collisions and S. Mohammed Hakkim v. National Insurance Co. Ltd. regarding the apportionment of negligence in sudden braking scenarios.

Regarding the tractor-trolley, the court applied the "principal cause" doctrine from Royal Sundaram Alliance Insurance Co. Ltd. v. Honnamma, holding that the motorised tractor is the causative agent of the accident regardless of the trailer's insurance status.

On the issue of licenses, the court followed National Insurance Co. Ltd. v. Swaran Singh and IFFCO Tokio General Insurance Co. Ltd. v. Geeta Devi, establishing that the burden of proving a "willful breach" of license conditions lies on the insurer.

Regarding contributory negligence, the court observed that while Rule 23 requires rear vehicles to maintain a safe distance, Rule 24 penalizes abrupt braking.

Since the eye-witness (PW-3) proved the tractor braked suddenly without indication to turn, the Tribunal’s 20% assessment was deemed a balanced "middle path" between the lead vehicle’s reckless maneuver and the rear vehicle’s failure to maintain reaction distance.

On the commercial use of the tractor, the court held that a trailer has no independent identity as a motor vehicle; since the insured tractor provided the motive force and initiated the braking, the insurer cannot escape liability simply because a trolley was attached.

Finally, regarding the license, the court found that the insurer failed to prove it was "fake." The mere non-availability of administrative records due to a fire/theft at the RTO (leading to FIR 334/2013) did not discharge the insurer's burden to prove the license was demonstrably invalid at the time of the accident.

The court further affirmed the 7.5% interest rate as consistent with bank rates for 2010. The balance amount was ordered to be disbursed to the claimants.
